GitOps Training

General

This is a complete project to train with GitOps metodology.

This repository provides a complete automated environment to deploy a functional infrastructure on AWS Provider and then we help to configure it step by step to understand and train with GitOps concepts.

Infrastructure

This tutorial, allow to deploy an infrastructure on AWS cloud. We will provision 4 EC2 servers with the following specifications :

• One GitLab CE hosted on a private EC2 host, with his own Docker registry,
• One Kubernetes cluster with one control plane node and two workers nodes.

This infrastructue is powered with Instrasdtructure as Code by AWS CloudFormation. We can use two type of files :

• AWS CloudFormation Stack File, to deploy your infrastructure in a basic plateforme AWS Cloud,
• AWS Educate CloudFormation Stack File, to deploy your infrastructure in a educative plateforme AWS Cloud.

To resume, these stack files use :

• AWS CloudFormation Stack File Description : AWS CLI, AWS Secret Manager, AWS IAM (instance profile), management Gitlab Registry certificate (generation end deployement)...
• AWS Educate CloudFormation Stack File Description : AWS IAM (instance profile), management Gitlab Registry certificate (generation end deployement)...

Every stack is detailed in depth. You can view more details about these stacks by clicking on AWS CloudFormation Stack File Description or on AWS Educate CloudFormation Stack File Description.

Project

In this tutorial, we will view how to implement tool chain integration with two GitOps approachs :

• Pipeline CI/CD with push approach,
• Pipeline CI/CD with pull approach.
